User equipment for supporting EN DC, and control method therefor

Abstract

A disclosure of the present specification provides a user equipment (UE) supporting a Dual Connectivity (DC) with Evolved Universal Terrestrial Radio Access (E-UTRA) and New Radio (NR). The UE may include a transceiver configured with the DC and configured to transmit an uplink signal and receive a downlink signal; and a processor configured to control the transceiver. Wherein based on (i) that the E-UTRA includes at least E-UTRA operation band 41, (ii) that the NR includes at least NR operation band 41, and (iii) that a band to be protected is a first band, the transceiver may be configured with a predetermined maximum level of a spurious emission.

What is claimed is: 
     
       1. A user equipment (UE), supporting Dual Connectivity (DC) with Evolved Universal Terrestrial Radio Access (E-UTRA) and New Radio (NR), comprising:
 a transceiver configured with intra-band non-contiguous DC, and configured to transmit an uplink signal and receive a downlink signal; and 
 a processor configured to control the transceiver, 
 wherein based on the intra-band non-contiguous DC being configured as E-UTRA operation band  41  and NR operation band n 41 , the transceiver is configured with a maximum level of a spurious emission, which is −40 dBm, for protected band E-UTRA operation band  30 , 
 wherein the E-UTRA operation band  30  includes an uplink frequency range of 2305 MHz to 2315 MHz and a downlink frequency range of 2350 MHz to 2360 MHz, 
 wherein the E-UTRA operation band  41  includes an uplink frequency range of 2496 MHz to 2690 MHz and a downlink frequency range of 2496 MHz to 2690 MHz, and 
 wherein the NR operation band n 41  includes an uplink frequency range of 2496 MHz to 2690 MHz and a downlink frequency range of 2496 MHz to 2690 MHz. 
 
     
     
       2. The UE of  claim 1 , wherein the maximum level of a spurious emission is based on a minimum bandwidth of 1 MHz. 
     
     
       3. The UE of  claim 1 , wherein the processor is further configured to receive a network signal related to an additional-maximum power reduction (A-MPR). 
     
     
       4. The UE of  claim 3 , wherein the maximum level of a spurious emission is based on the network signal related to A-MPR. 
     
     
       5. A method for controlling a transceiver of a user equipment (UE) supporting Dual Connectivity (DC) with Evolved Universal Terrestrial Radio Access (E-UTRA) and New Radio (NR), the method comprising:
 receiving a downlink signal by controlling the transceiver, 
 wherein the transceiver is configured with intra-band non-contiguous DC; and 
 transmitting an uplink signal by controlling the transceiver, 
 wherein based on the intra-band non-contiguous DC being configured as E-UTRA operation band  41  and NR operation band n 41 , the transceiver is configured with a maximum level of a spurious emission, which is −40 dBm, for protected band E-UTRA operation band  30 , 
 wherein the E-UTRA operation band  30  includes an uplink frequency range of 2305 MHz to 2315 MHz and a downlink frequency range of 2350 MHz to 2360 MHz, 
 wherein the E-UTRA operation band  41  includes an uplink frequency range of 2496 MHz to 2690 MHz and a downlink frequency range of 2496 MHz to 2690 MHz, and 
 wherein the NR operation band n 41  includes an uplink frequency range of 2496 MHz to 2690 MHz and a downlink frequency range of 2496 MHz to 2690 MHz. 
 
     
     
       6. The method of  claim 5 , wherein the maximum level of a spurious emission is based on a minimum bandwidth of 1 MHz. 
     
     
       7. The method of  claim 5 , wherein the processor is further configured to receive a network signal related to an additional-maximum power reduction (A-MPR). 
     
     
       8. The UE of  claim 7 , wherein the maximum level of a spurious emission is based on the network signal related to A-MPR.
